It is possible to print directly onto the embroidery stabilizer. Yes, really
This is what I did:
I cut a piece of stabilizer and a piece of freezer paper to exactly A4 size (to make sure it doesn't get eaten by the printer) and ironed the two together.
I then put it in the printer with the stabilizer (print side) facing down and printed as normal. I don't have the best printer in the world so I was prepared for things to go terribly wrong here, but everything worked out perfectly.
I peeled the stabilizer off and voila: A perfect embroidery-pattern ready to start stitching!
I made a sketch of the photo because I made a few changes to the original picture, but it is possible to print the photo directly onto the stabilizer too.
Now no more light boxes and window tracings for me! Yippee!! (You can see why I was looking for an easier way to copy the picture, can't you?)
As you probably know by now, I am a completely self-taught embroiderer. Except for some help from my mother and grandmother when I was still small, I never had any formal embroidery training. Now you can understand why I am so thrilled with this discovery - I figured it all out by myself and it is going to make my life a lot easier.
